Problem 10
Which one of the following statements about free bosons, fermions, and classical particles is correct?
(A) Bosons possess integer spin and follow the Maxwell-Boltzmann distribution in the low-temperature regime.
(B) Fermions are indistinguishable particles that obey the Pauli exclusion principle and follow the FermiDirac distribution in all temperature range.
(C) Classical particles can either be distinguishable or indistinguishable depending on the type of atoms or particles.
(D) In the low-temperature limit, bosons and fermions cannot occupy the same quantum state, in contrast to classical particles.

(E) In Bose-Einstein condensation, particles follow the Bose-Einstein distribution, with most particles occupying either the same excited state or the ground state. This phenomenon can be observed macroscopically.
